The last 3 years, I used a 6" Lone Wolf Barrel, and my load was, using a 200 grain hardcast, on top of 8.2 grains of Longshot. I achieved 1250 fps with this setup. Last winter I sold the LW tactical length slide, and 6" barrel, and recently purchased the LW tactical length barrel to just drop in my 3rd Gen G20. The accuracy is splendid, but have not chronographed as of yet, but am confident this setup will do nicely. I have recently picked up some 180 hardcast that I plan on using in the future. One of these days I'm going to make my own bullets, and want the bullet molds to have as much versatility as possible. If the 180's run in both the 10, and 40 well that's the route I'll take with a mold. Don't care for 200 grain in the 40.
